How do I get the editor to preview .rst files (reStructuredText)? It does a Preview for .md (MarkDown). What's even more interesting is that if I rename my .md to .rst, I still get the preview window (the Text/Preview tab at the bottom of the window) AND it previews .rst correctly. It's just that when I reload PyCharm it doesn't give me a preview window for .rst.

It seems to be keying off of the file extension, but only providing Test/Preview tabs for .md and not .rst, even though the Preview actually supports .rst.
